普瑞巴林（Pregabalin），是一种治疗癫痫、神经痛、纤维肌痛、广泛性焦虑症[1][2]的药物。

药理学

普瑞巴林是神经递质γ-氨基丁酸的衍生物，[3] 也是一种强效的加巴喷丁类物质，但它并不与任何γ-氨基丁酸受体结合，而是通过抑制钙通道发挥作用。[4][5]它是某些电压依赖性钙通道（VDCCs）的辅助α2δ亚基位点的配体，从而作为含α2δ亚基的电压依赖性钙通道的抑制剂。[4] [6]它与α2δ1以及α2δ2这两个亚基结合，并在这两个位点上表现出了相似的亲和力，因此普瑞巴林缺乏α2δ亚基的选择性，[4]但具有电压依赖性钙通道的α2δ亚基选择性。[6] [7] 虽然普瑞巴林不与任何γ-氨基丁酸受体结合，也不会转换为γ-氨基丁酸或其他γ-氨基丁酸受体激动剂，也不直接调节γ-氨基丁酸的转运或代谢，[5][6]但它会增加L-谷氨酸脱羧酶（GAD）在大脑中的表达，[8][9] [10] 而此酶是用于合成γ-氨基丁酸的酶，因此可能由于大脑内γ氨基丁酸水平升高造成一些γ-氨基丁酸能的作用。但目前没有证据可以说明普瑞巴林的作用是除了抑制含α2δ亚基的电压依赖性钙通道介导的。[6] [11] 因此，普瑞巴林对其的抑制作用似乎是它抗惊厥、镇痛和抗焦虑效果的原因。[6][11]


在一项研究中发现，普瑞巴林对含α2δ亚基的电压依赖性钙通具有比加巴喷丁高6倍的亲和力，[12][13]而在另一项研究中发现，普瑞巴林和加巴喷丁对人类重组α2δ1亚基具有差不多的亲和力（Ki分别为32 nM和40 nM）。[14]在任何情况下，普瑞巴林作为镇痛药的效力是加巴喷丁的2~4倍，[3][15]在动物身上作为抗惊厥药时的效力似乎是加巴喷丁的3~10倍。[3][15]

滥用

普瑞巴林因其中枢抑制的特性时常被滥用，通常会使用至少一次300mg或更高的剂量。普瑞巴林在过量时可能具有成瘾性和戒断反应。
